The Derrico quintuplets that made headlines with their birth last fall are now 4 months old and going through a staggering 40 bottles and more than 100 diapers a day.

Today.com stopped by the Las Vegas home of the Derrico family, which grew from four children to nine in September when the quints arrived. Parents Evonne and Deon already had 8-year-old Darian, 3-year-old Derek, and 2-year-old twins Dallas and Denver, who now help out with their little siblings Deniko, Dariz, Deonee, Daician, and Daiten — four girls and five boys in total.

The quints spent their first few weeks in the hospital but now they're all settled in and generating a lot of diapers to change.

"You change 'em, you finish and go to the next one, and then realize the one you just changed did it all over again," Derrico said.

To make room for their growing family, the Derricos converted their home theater room into a nursery, but are still trying to figure out their vehicle situation, as a standard minivan won't fit everyone.

Raising kids is expensive but Deon Derrico, a property manager for a real estate company, said that's not his main concern.

"I don't want any of them to grow up thinking they didn't get enough love," he said.
